alternative from mk/jpeg.buildlink3.mk
This allows selection of an alternative jpeg library (namely the x86 MMX,
SSE, SSE2 accelerated libjpeg-turbo) via JPEG_DEFAULT=libjpeg-turbo, and
follows the current standard model for alternatives (fam, motif, fuse etc).
The mechanical edits were applied via the following script:
#!/bin/sh
for d in */*; do
[ -d "$d" ] || continue
for i in "$d/"Makefile* "$d/"*.mk; do
case "$i" in *.orig|*"*"*) continue;; esac
out="$d/x"
sed -e 's;graphics/jpeg/buildlink3\.mk;mk/jpeg.buildlink3.mk;g' \
-e 's;BUILDLINK_PREFIX\.jpeg;JPEGBASE;g' \
< "$i" > "$out"
if cmp -s "$i" "$out"; then
rm -f "$out"
else
echo "Edited $i"
mv -f "$i" "$i.orig" && mv "$out" "$i"
fi

* Huge new documentation in Info, PS, PDF, and XHTML formats. Plain
HTML format is not supported because it cannot portably render MathML.
* New manual pages.
* Automatic bit depth conversion between input and output images if
necessary.
* Compilation without image cache works again
("--disable-image-cache"). Speedups of up to 30% have been reported
on the amd64 architecture.
* Enblend and Enfuse accept repsonse files in addition to literal
image files. Response files contain lists of image filenames or
names of other response files.
* Lots of new warnings if a command-line option has no effect, like,
for example, combining a mask optimization option with "--no-optimize".
* Enblend shows the initial, unoptimized seam line in addition to the
optimized one in all seam-line visualization images (option "--visualize").
* Enblend and Enfuse read multi-layer TIFF files ("multi directory" in
TIFF jargon). It is even possible to mix multi-layer with single
layer images. This partially fixes SourceForge bug ID 1170329.
* Save masks with (lossless) "Deflate" compression.
* An improved wrap-around option, formerly only "-w", now "-wMODE" and
"--wrap=MODE", lets the user determine whether to create a 360
degrees horizontal or vertical panorama. It is possible to wrap
around vertically and horizontally at the same time.
* Without any output filename given, i.e. no "-o" option, the output
filename now defaults to "a.tif", making "-o" truly an option.
* The user has better control of the number of pyramid levels.
Previously only the maximum number in any blend could be reduced
by the "-l" option. Now, the maximum number can be reduced by a
fixed amount no matter what the actual maximum number of permissible
pyramid levels is.
* Use OpenMP to make better use of multi-processor machines. As the
image cache is not reentrant, OpenMP can only be activated when the
image cache is disabled.
* Enblend and Enfuse issue messages following the GNU standard.
* Bug Fixes
seams. Enfuse combines images that overlap like this into a single image with
good exposure and good focus. Both programs assume that your images are already
lined up. To make panoramas with Enblend and/or Enfuse, use Hugin.
